No. 4: Kory Sheets

Coming to the Raiders as a free-agent addition from the Canadian Football League, Kory Sheets will be an interesting player to watch throughout training camp and the preseason.

In the 2013 season, he tallied 1,598 rushing yards and 12 touchdowns in 15 games, helping his Saskatchewan Roughriders to a Grey Cup title.

With the CFL being the three-down league that it is, and thus often centered around the passing game, rushing numbers like that become all the more noteworthy.

While a transition from the CFL to the NFL can be a difficult one, there are a number of players that have seen their careers take off after a few years north of the border.

Unfortunately for Sheets, he joins a rather crowded backfield in Oakland. However, depth at running back is extremely important for any team, and he will have every opportunity to show what he is capable of now back in the NFL.

Starter: Maurice Jones-Drew

Heading into his ninth NFL season, at 29 years old, Maurice Jones-Drew joins the Raiders looking to prove he still has plenty left to offer.

Although he has struggled with some injuries in recent seasons, he has still shown flashes of the productive player he established himself as in the years prior.

Now past those injuries and entering a wide-open running back competition, Jones-Drew will have the opportunity to earn the Raiders’ starting job heading into the regular season.

Although this backfield is likely in for a fluid rotation regardless, that chance to compete is something that was attractive to Jones-Drew when joining the Silver and Black.

At this point, Jones-Drew projects to see the most snaps of any back in the group based on his vision, power and ability as a pass protector in the backfield.

Either way, he and McFadden’s running styles complement each other well, and if both can stay healthy throughout the season, the Raiders could have quite the productive group of running backs to carry the offense.
